- NITED STATES PATENT EEIOE RIGHT TO HENRY WARREN HOWE, OF SAME PLAGE.

IMPROVEMENT IN MITER-BOXES.

specification forming part of Letters Patent N0.i1s7,712,dated February27, 1817 application ined August 23, 1876.

To all whom it may concern:

Be it known that I, JAMES M. JONES, of

Lawrence, in the county OfDouglas and State' of Kansas, have invented anew and useful Improvement in Miter-Boxes, of which the following is aspecification, reference being had tO the accompanying drawings.

This invention relates to an improvement in miter-boxes,and consists inthe mechanism hereinafter specifically designated, its object being toprovide an adjustable device for mitering purposes.

Figure is a plan view of a device embodying the elements of theinvention. Fig. 2 is a rear View of same. Fig. 3 is a central verticaltransverse section of same.

In the accompanying drawings, A represents a bed-plate or base restingupon the cleats B, and provided On its rear end with the backing D,which is provided at about its vertical center with the slot E, adjacentto which the bed-plate A is cut away to receive the plate or stand F,secured in position by rivets or set-screws passing through elongatedapertures or slots formed in the lugs H, so

'that the plate can be slightly raised or lowered, as occasion requires.

The bed-plate A may be .Of any suitable configuration, but it ispreferred to have the contour-of the front edge either oval or circular,as by the use of' this form the adjustable shoes Or clampsI can be morereadily brought to line with "the swiveled rollers L, and thusfacilitate the Operator in obtaining the desired l angle.

j placed a suitable distance apart, and provided With the roll-ers L.These rollers are loosely mounted upon the standards V, so as to have arotary movement thereon, and thus facilitate the passage of the sawbetween them.

The clamps I are secured at suitable points upon the front edge of thebed-plate A by the set-screws a and lips b, and are provided with theslots d, which are cut in the upper lip b,

so as to prevent the saw from becoming inany suitable point opposite therollers L to Obtain the angle desired, the other two clamps beingfurnished more for convenience than positive requirements.

The standards V, being rigidly secured upon the swivel N, the rollers Lmay be turned so asto face either of the rollers e, and thereby permitthe saw, when in Operation, to be placed inv the space between therollers L and rollers e, thus preventing it from making an 'untrue orimproper cut in the material placed on the bed A between the rollers eand backing D.

In the slots or grooves f out in the bedplate A are provided theapertures h, in

which pins may be driven and replaced for e the purpose of preservingthe bed-plate from the eii'ects'of the saw.

What I claim as my invention, and desire to secure by Letters Patent,is-

The slotted clamps I, provided with the standards W and rollers e, incombination with the stand F, swivel N, provided with the standards Vand rollers L, and bed-plate A, all constructed to operate in the mannershown and described, and for the purpose specified.

In testimony that I claim the foregoing improvement in miter-boxes, asabove described, I have hereunto set my hand this 9th day of August,1876.
